Less than 2 years ago, I bought and had Velasquez Mufflers and Brakes install a Flowmaster muffler, knowing full well that they come with a 3 year warranty. I brought it back to them yesterday since there's a crack in the muffler (likely due to being installed wrong ie: without an extra hanger to support the weight). They flat out refused to fix/replace the issue under the manufacturer's 3 year warranty saying "our distributor only gives us one year" which is flat out bull$#!+. I gave them several opportunities to fix the problem, including welding a patch over the crack as a temporary measure. They refused. I took my keys while it was on the lift, and told them that I'm not leaving until the job is done. They STILL refused and called the police (who agreed with me, btw). Avoid these guys like the plague. They will NOT stand behind the manufacturer's warranty, and if you have a problem, you're SOL. I called Flowmaster who said that they're not authorized vendors, and they will be making sure that Velasquez Mufflers removes the Flowmaster signs from their site as well as remove their links to the Flowmaster sites on their website.
